We have just purchased and completed the installation of an inground fiberglass pool with a built in spa from Leisure Pools. The pool is called The Ultimate The Ultimate | Leisure Pools USA The spa is heated and can be controlled independently of the pool so when we close it this year (soon) we will keep the spa open year round. I am almost 100% positive the spa when operated independently does not go through the salt system (checking with pool builder as we speak). Having said that, what are some alternatives to close the pool over the winter season, while keeping the spa chlorinated? Could I have a floating chlorine dispenser in the spa or any other/better recommendations?
